1 Claim.

This invention appertains to new and useful improvements in frames or masks used in printing photographs.

The principal object of the present invention is to provide a mask which in use will produce straight borders on prints with which the same is-used.

Another important object of the invention is to provide a mask of the character stated constructed in such a manner as to hold a print from sliding or displacing in any way.

Another important object of the invention is to provide. a printing mask for printing photographs which includes a back against which the contact paper is first placed and thereby protect against scratching or other damage.

Other objects and advantages of the invention will become apparent to the reader of the following description.

In the drawing:

Figure 1 represents a top plan view showing the back side of the mask.

Figure 2 is a top plan View showing the front side of the mask.

Figure 3 is an enlarged fragmentary detailed sectional view.

Referring to the drawing wherein like numerals designate like parts, it can be seen that the mask includes a frame 5 and a back 6.

The frame consists of a sheet of suitable material having a rectangular or other shaped exposure opening I therein and having the longitudinal edge portions thereof disposed inwardly to provide flanges 8, 8 and these flanges define a vguideway 9 for the back 6.

One end of the sheet is folded inwardly to define a flange l0 against which one end of the back 6 can abut.

Obviously, the back 6 can be slid outwardly and against this can be placed contact paper and on the outside a negative (not shown). The back,

contact paper and negative can then be slid inwardly of the mask for the purpose of printing the picture and in this position, the negative will be on the outside and the contact paper protected between the negative and the back 6. Further, the marginal portions a, b, c and d will define on the resulting picture a straight border, which is at present difficult to produce with the equipment now generally used.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
